He finally has some length to his stride and his back is moving, but he is now locked onto that bit like he thinks it's actually going to hold him up. Dude, you're 1,350 pounds to my 124 - ain't no way I am holding you up! The other thing I am wrestling with is his wayward right shoulder which is actually great since that's the same issue I have with Speedy. I now get to work on it ALL. THE. TIME.
The difficulty is that he wants to be spooky which means strong reins on my part to keep him from veering off - usually to the right. I also had to use the whip to make my leg aid loud enough for him to hear. Eventually, I brought everything back down to a walk so that I could control the forward while insisting with my leg/whip that he step OVER.
He never makes things easy, but for a thinking rider, he'll give you plenty of puzzles to solve. I just put one more piece in the puzzle.
